Can you expand this comment to explain why having a script for this is necessary
in the first place? From reading just this file it would seem really random.

Done.

+# Usage: RedirectStdout.sh <command> <output file>

Can you change this from a comment to a real usage check that looks for two
arguments and prints usage info if there aren't? I know people aren't likely to
just try running it, but there's no reason not to.

Done.

+#
+# Example: Write the text 'foo' to a file called out.txt:
+#   RedirectStdout.sh "echo foo" out.txt
+
+exec $1 > $2

[stuartmorgan, 2012/07/20 07:45:44]

We should quote $1 and $2

Done.
